Jasmine日期总是会返回false

Question

我有一个用Jasmine测试运行器编写的测试：

it("Expect 'due date' to be 14 days from today", function () {
    var dateNow = new Date();
    scope.dateOfService(dateNow);
    expect(scope.DueDate == new Date(dateNow.setDate(dateNow.getDate() + 14))).toBeTruthy();
 });

但是这总是返回false？我有什么不对的吗？

要调试＆＃39;我也跑了：

expect(scope.DueDate).toBe(new Date(dateNow.setDate(dateNow.getDate() + 14)));

然后返回：

Expected Date(Tue Nov 11 2014 08:20:23 GMT+0000 (GMT Standard Time)) to be Date(Tue Nov 11 2014 08:20:23 GMT+0000 (GMT Standard Time))

Answer 1

var dateNow = new Date();
scope.dateOfService(dateNow);
var dateReturned = new Date(scope.DueDate);
var dateAdd = new Date(dateNow.setDate(dateNow.getDate() + 14));
expect(dateReturned).toEqual(dateAdd);

重点是确保它是.toEqual而不是.toBe。
